    • The CMDB CI Class Models store app adds or updates classes for Red Hat Virtualization (RHV).

    The app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and dependent relationships if applicable. You can use the added classes as any other CMDB class. Applications such as Discovery and Service Mapping patterns can use these class extensions to populate CIs and discover various technologies and software.

    Red Hat Virtualization (RHV)

    Red Hat Virtualization (RHV) is a virtualization product which is based on the Kernel-based Virtual Machine (KVM) hypervisor. RHV uses the SPICE protocol and Virtual Desktop Server Manager (VDSM) with a RHEL-based centralized management server. RHV solution is based on two primary software components: Red Hat Virtualization Manager (RHV-M) and Red Hat Virtualization Hypervisors or hosts: Red Hat Enterprise Linux or RHV Host (RHV-H).
